Air Dryers

In compressed air Dryers, two vessels filled with desiccant is provided which cycle automatically, producing dry air continuously. In these units, wet air enters the bottom of one Vessel and passes upwards through the desiccant bed where the moisture is adsorbed. The clean dry air comes out from the top. A small portion of dry air is passed downwards through the desiccant bed in the second vessel which is under re-generation. The moisture-laden purge air is then vented out to the atmosphere.The purge loss is around 7.5% of the total air flow. At the preset interval, the vessel changeover automatically, and the Dry air is available continuously without any surges.

Easy Operation:

This is simplest type of air dryer with Activated Alumina / Molecular Sieves drying agent. This is virtually maintenance free, fully automatic, and requires no attention for year. compressed air type dryers do not require any heating re-generation and therefore are very simple in design and maintenance free.

Advantages:

• Due to its inherent simple design, investment in this type of dryer is the cheapest and the payback on this investment is very quick
• Low-Temperature operation reduces corrosion in tower and desiccant lasts longer
• Power requirement is 60 watt only for Solenoids Valves Operation

Operating Principle:-

In Heatless Dryers, two vessels filled with desiccant is provided which cycle automatically, producing dry air continuously. In these units, wet air enters the bottom of one Vessel and passes upwards through the desiccant bed where the moisture is adsorbed. The clean dry air comes out from the top. A small portion of dry air is passed downwards through the desiccant bed in the second vessel which is under re-generation. The moisture-laden purge air is then vented out to the atmosphere.The purge loss is around 7.5% of the total air flow.

We are offering Refrigerated Air Dryer having air capacity of typically above 500 NM3/ hr for lager air drying capacities. It is a skid mounted unit consisting of air-Freon chiller air to air pre-cooler and a moisture separator. In this, first air is pre-cooled with outing chilled air at around 25°C and then it is cooled in a Freon cooler at (+)3°C temperature and hence reduces power consumption. Outgoing dry air has (+)3°C dew point and comes out at around 25°C temperature, as (+) 3°C Dew Point is equal to around (-) 25°C Atmospheric pressure Dewpoint.

Dew Point:

(-) 25°C is the best possible Dew Point achievable from Refrigerated Air Dryers. Lower Dew Point is not possible from Refrigerated Dryer as moisture condensed would start freezing on Freon tubes if the lower dew point is tried. This (-) 25°C Dew Point is adequate for most dry air applications and instrument air requirements.
